How many times in a day hour hand and minute hand of a clock pointing opposite to each other?

22

The hands of a clock point in opposite directions (in the same straight line) 11 times in every 12 hours. (Because between 5 and 7 they point in opposite directions at 6 o'clock only).

So, in a day, the hands point in the opposite directions 22 times.

The correct answer is Option (4) → 22
